摘要: 反应堆压力容器（Reactor Pressure Vessel，RPV）长期工作在强中子辐照环境下，材料会受到辐照损伤，从而影响其使用寿命。针对这一问题，基于磁巴克豪森噪声（Magnetic Barkhausen Noise，MBN）效应原理，建立巴克豪森传感器的三维仿真模型，仿真结果验证了传感器结构的有效性，确定了传感器的最优参数。同时以TMS320F28335开发板为核心研制了一套针对小尺寸RPV钢辐照脆化的便携式检测系统，验证了该系统的重复性与稳定性。Abstract: Reactor pressure vessel (RPV) operating under intense neutron irradiation for a long time will suffer radiation damage, which will affect its service life. Aiming at this problem, based on the principle of magnetic Barkhausen noise (MBN) effect, a three-dimensional simulation model of Barkhausen sensor is established. The validity of sensor structure and its optimal parameters are verified by simulation results. At the same time, a portable detection system for irradiation embrittlement of small size RPV steel is developed, which is based on the development board of TMS320F28335. Then, the repeatability and stability of the system are further verified.
